$servername = "localhost";
$username = "root";
$password = "123456";
 $dbname = "mysql2";
 
// 建立連接配接
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢測連接配接
if ($conn->connect_error) {
    die("連接配接失敗: " . $conn->connect_error);
} 
 
$sql = "INSERT INTO mysql3 (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]')";
 
if ($conn->query($sql) === TRUE) {
    echo "新記錄插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
 
$conn->close();
